'stop mechanism; The object of said inven-- tio n is to rovide simple and eflicient neehansn-of t echaracter specified. "To the above and other ends which will hereina'fter ap' ear, my inventionconsists in the features o construction, arrangements of tits combinations of devices to be reinaft'er described and claimed.

In;the accompanying drawings, Figure 1' isa front to reat' vertical sectio'nal V ew of part of the typewriting machine with the stop mechanism of. myinvention appli thei-eto. Fig. 2 is an enlarged detail perspective view of a margn stop constructtfm invention. Fi 3 is a similarwiewof a e lock sto em odying my invention. Fig. 4 is an en arged deta tive view of a looking member and ts spring applicable to either of the stops shown in Fgs. 2 and 3. verse sectional view take ough a stop, looking member and stop rod; the part be- 'ing shown assembled in this view. Fg. 6

is.. detail fragmentar front elevation of aupon the stop rod. Fig. 7 is a like view of the Iine lock'stop-and the associated parts.

While I have shown my invention applied to a front-strike machine it should be understood that it may be'em loyed .in various styles of typewriting mac 'nes The frame of the 'machine comprises 'a base Lpovided with corner posts 2 and 'a top= pla 3. The frame supports grooved ide rails 4 which .coperate with anti-frieton balls or rolls received' in grooves in bars 6 of e platen-carriage 7, a platen being indicated at 8. Projecting rearwardly fromthe carriage near each end thereof are bracket arms 9 which support a stop bar 10 The stop bar is of dove-tail form wth the inclined sides 11 and 12 Situated 'respectivelyat the top and bottom. ;The'bar is recssed at one sde throughdut its length, as ndcated at 13. The inclned side or face 11 of the' stop bar is provided. with a scaleior indices 14: by which the na'gin stop 15 and hne lock stop 16 may roperly be set as' will lereinaftcr more clear y appear..

The margin stop 15 has a dove-tail o enmg 17 extending longitudinally thereofor the reception of the stop bar, the groove or opening 17 beingopen ut the forward side of the stop. Extendng at right angles to the 'gi-cove 17 is a dove-tail groove 18 which extends transversely through the stop and is adapted to receive a dove-tail locking device 19 shaped .to conform to and adapted .to

"slide in the. opening 18 transversely. of the slot or groove 17.

The lower end of the looking member is provided with teeth 20 which co-act with, teeth 21 formed at the lower edge of the stop .bar in order to lock the stop against lon 'tudinal movement on the. bar. The

'teet 1 20 of the 'looking device are normally maintained seated between .the teeth 21 of the stop har by a s ring 22 which is coiled at the center thereo as at 23 about a pin 24 which projects orwardly from thelocking member. The free ends of this spring' 22 bear ortop of ins 25 which project forwarly from the edy' of the stop andinto the dove-mil groove 17 thereof.

A projecting lug or stop face 26 is 'provided on the margin stop for. coperation with suitable co-acting means on -the frane of the machine for arresting the carriagein its movement to the right. An indicating -edge 27 is provided on the margin stop for coperation with thc indices 14 of the scale on the sto'p bar in order to facilitate the pro er settng of the margin stop( roman inspection of Fig. 5 it will be seen that the pm 24 by which the sging 22 is connected with the looking mem r. pro jects into the recess- 13 in the stop bar and is adaptedto abut .the inner lower face of said. recess *to limit the downward movement of:

'the lockin member 19, the lu ward movement of tie locking member eing limited bythe contact of the teeth 20 with the bottom walls 28 of the spaces between the teeth 21 of the sto bar.

In' assemb n the prts the looking mem 'ber 19 'with te spring 22 disconnected therefrom ,is first moved upwardly into the dove-tail ..groove 18 and the loop 23 of the spring 22 is then placed on the pin 24 and the free ends of the spring are have been placed on the bar as described' and Sprung into posit on on top' of the pins 25. the bar Secured to the carrage 'there is` no The looking member-s then depressed so liablity of the parts becom'n detached, 'as to carry the teeth 20 out of the dove-tail deranged or broken. It will also be seen .5 groove 17 of the stop and the stopbar is ithat' by placing the scale on the face '11 of 70 troduced nto the dove-tall groove 17; the' dove-tail -stop bar an inclined face is When pressure lS released on the looking presented for the scale which ma be readily member 19 the pressure oi" the spring 22 viewed by the operator as will b e apparent wll force it' upwardly, thereby ringig the' from an inspecton of ig. 1, thereb faciliteeth 20 -on` the looking member into engagetating a properadjustment of the lne lock 75. munt with' the teeth on the stop, bar to lock 'and mar in steps'. the stop in thedesired posit on. What claim as. new and desire-to secure The 'line lock stop is -formed in the *same by Letters Patent, is z 'eneral manner as the margn stop; Thus 1. In a typewriting machine, the combinat e stop 16 hasa longitudinally extending tion of a stop having a dove-tail-groove so dove-tall groove 29' and a dove-tail groove therein, a stop bar slaped to be reoeivedin .30 extendmg at right ngles to the first said dove-tail groove and havin a reoess in mentioned groove or the reception of a one face thereof, e locking-latoE-carried by looking member 19. Pins-3lgare provided' said stop and operative to 'lokthe stop to for coperation with the spring 22. -An insaid bar, and a spring for said latch, said 35 "dicating edge 32 'coperates with the indices .spring being' received in the recess in:` said on the scale ofthe stop bar. A line lock bar., I V Operating rojection 33 extends dow'nwardly -2. `In atypewriting machine, the combine- `from the 'fine lock stop and co-acts' with a tion of a stop having dove-tail grooves there member 34 to efl`ect an actuation ofthe line in at substant-iallyrght angles to each' other, 90'

A trip.35 is,pivoted by a a 'dove-tail stop' bar received 'in one of the headed' shouldered screw 36 "to the rearside' dove-tail grooves in' said stop'and rovided of the line look stop 16. A pin 37 projects with teeththereon and a. recess a ong one from the rear face of the stop. 16 and is reside thereof, a' dove-taillocking member rel- 0. .ceived in an' o 38 between two arms ceived in the other dove-tail groove in the 95 'or sto s"39 and '40 respeetively of the trip` stop and provided with teeth which engage in o er -to 'limit th'e movem t of `the trip 'the teeth onsaidstop bar, and a spring inaround its pivot. The arm 39 of the trip co- -termediate said stop and lockin member 4 operates w'th a bell trip'41 operatively conand contained in the recessin sai stop bar. n ted to the alarm mechansmg 4 3.
